LAMINAR VS TURBLENT FLOW

Laminar flow
Laminar is a fluid flow in which the fluid travels smoothly or in regular paths. The pressure and other flow properties at each point in the fluid are constant. Laminar flow over a horizontal surface may be thought of as consisting of thin layers, all parallel to each other, that slide over each other. It is common only where the flow channel is relatively small, the fluid is moving slowly, and its viscosity is relatively high. Examples include the flow of oil through a thin tube and blood flow through a blood vessel .
Dolphins use Laminar flow
Dolphins use laminar flow because it has a sleek back that helps it cut through the water efficiently and at the top speed of 25 miles per hour when in a hurry, or swim roughly 7 to 8 miles per hour . The air is not distracted a whole lot and so, it doesn't cause any obstacles for the dolphin to slow down .
Airplanes use Laminar flow also !
Air planes and Dolphins are very similar when it comes to laminar flow they both have a brim to cut through the the water and air while making movements . I believe if airplanes didnt have wings the plane wouldn't be able to fly as smoothly and land properly as usually because the wings of the plane keep the plane in balance. If a plane had no wings while landing it would go straight down and will probably crash .
What is turbulent flow ?
Turbulent Flow
Movement of a fluid in which subcurrents in the fluid display turbulence, moving in irregular patterns, while the overall flow is in one direction. Turbulent flow is common in nonviscous fluids moving at high velocities and considerable mixing occurs .
For example when you turn on the tap , the water that splashes around the sides then goes through the drain is known as turbulent flow. Or when water is going the other direction from the pipe , water is coming out instead of going in. The water is spitting out and coming at a high speed and not all coming out it the same direction .
